Should I trade Welker straight up for L. McCoy? Its a 3wr, 2rb, 1flx PPR league and I'm stacked at WR (Wayne, Bowe, Nelson, D. Jackson, Sanders, Thompkins) but weak at RB (Bush, Sproles, Bernard, and Miller).

I hate to lose Welker's upside, but I can match his point totals from one of the back ups. McCoy would start at Flex, pushing Bowe to the bench. Not a bad back up.

The other guy has P. Manning, which is why the trade is being discussed.
